About These Birds
Tufted Duck
A small compact diving duck. Males are boldly black-and-white with a drooping crest; females are brown with a shorter crest. Common and widespread across Eurasia. Males are highly distinctive. Dives for molluscs, invertebrates, and plants in freshwater and coastal habitats.
Black Swan
The black swan was once considered impossible by Europeans who believed all swans were white, making it a famous philosophical example of inductive reasoning failure. It is the state emblem of Western Australia. Black swans form lifelong pair bonds and both parents share in incubation and care of cygnets.
